How to define multiple distinct controllers in Grails 2 filter?

Question

Is it possible to define multiple distinct controller in a Grails 2 web application filter? For example, something like:

def filters = {
    someFilterMethod         


        

Answer 1

If you can define a rule that matches index.gsp, then you can define a rule that matches everything but index.gsp by adding invert: true. I guess something like this should do it:

def filters = {
    someFilterMethod(uri: '/', invert: 'true') {

    }
}

It seems like the following should also work:

def filters = {
    someFilterMethod(uriExclude: '/') {

    }
}

You can provide a regex instead of a literal path, so if you also need to exclude '/index' as well, then you just need to replace '/' with a regex that matches '/' and '/index'. My regex skills are rusty, but something like this should do it:

def filters = {
    someFilterMethod(uriExclude: '/(index)?', regex: true) {

    }
}

Warning

I haven't tested any of the code above, so caveat emptor!
